[QUOTE="Jeffdachef, post: 8721400, member: 650438"] DSP acts as a digital crossover that you can choose any frequency from 20hz to 20khz high pass, low pass, bandpass, slope control, type of crossover aka linkwitz, bessel or butterworth etc... tweeters usually handle 3000hz-5000hz and above, midrange around 250 to 3000 and midbass is 80 to 250hz each driver does its own job which allows better separation and clarity and output. Yes you can do a coaxial but thats playing the sound quality lottery so if you are a gambler feel free. I prefer 100% guaranteed results. test the impedance of the speakers with a multimeter, if they are 4 ohms then on the 1st 4 channel amp you can wire all left tweeters to channel 1, all right tweeters to channel 2. All left mid to channel 3, all right mids to channel 4, Now the next 4 channel amp you can wire all midbass speakers to channel 5 and 6. Now with with the channel 7 and 8 and you last amplifier channel you can bridge that for a low powered dual 2 ohm or single 4 ohm subwoofer. You wont have front and rear fade capabilities but you'll have much better sound quality overall due to having full control over the sound. [/QUOTE]
